We are a commercial refrigeration company looking to design a proprietary controller based on open architecture software / hardware. The project will require in-depth knowledge of sensor inputs relay outputs and graphical data display of multiple values from the sensor inputs. Control operation will be based on provided logic applied to sensors and

...battery monitor with alarm management, high precision requested on pressure reading with 4-20 mA sensor. The system must detect errors on pressure probe. Design and production of PCB also required. PCBdesign must be don with Eagle Soft. Has to be applied to racing vehicles so must withstand strong vibrations and temperature swings.
Build and delivery of

...another one each day, and unplug the previous one, and plug the new one)
about the work :
->design the circuit, list the components / parts required, write the code, maybe suggest others things to use
->test it on your side until it works well
->send me the schematic of the circuit, and the code to control the board, and instructions to assemble the circuit

...someone to peer review for electronic design to be compliant with CE and FCC.
First phase: analyse schematics, identify possible issues which may affect safety of device or non compliance with CE, FCC regulations, make sure that all elements are compliant with RoHS regulations.
Second phase: analyse PCBdesign for correctness in accordance with CE

...controller board.
Relay and mcu is blowing up after sometime.
Need to fix relay and add transistor so that it does not blow up and blow controller board.
Need to provide schematic and wiring ,need to help if any problem during assembly and testing.
it should be perfectly working 24x7
It should not take more than an hour to provide solution for expertise

We are working on a project involving de...differentiate and warn the driver of black ice and we also can’t use arduino, need a micro controller similar to atmega8 something along those lines.
We need a complete schematic telling how to make the connections and the procedure.
Also, a list of which parts to use for this project and why to use them.

...like to design a motorized Iron Man Faceplate system using two Hitec metal gear servo that uses between 4.8 to 6v. It will use an Arduino Uno w/ Adafruit "Music Maker" MP3 Shield for Arduino w/3W Stereo Amp - v1.0 for sound effects as well as to control the leds eyes in the faceplate . This individual will need to design the circuit layout in detail

I am Looking for an engineer that can update the Schematic and PCB of an audio board.
Need to Update/add connectors such as MIDI connectors, audio connectors, USB, memory, board size, etc
The PCB is in CADstar format, The Schematic is in Orcad format.
I have schematics and PCB files, I you have CADstar is a Plus.
Our Organization shall keep the rights

Need only schematicdesign and BOM file using Altium Designer. I want to make POE circuit design for Raspberry Pi 3. It must be capable of supplying over 70W power for the device to be controlled.
Relevant freelancer who can handle this project smoothly will be awarded PCBdesign by next project.
Thanks.

...clean) on a fixed time.
We have a Control PCB which has 10 Digital Inputs , 2 Analogue Inputs & 4Digital Outputs in each cleaning system which will work on Modbus protocol to communicate with your software.
PC which has the control software is connected to Data transmission unit(DTU) which connects with control PCB in wireless connectivity.
Each input status

We will supply files for 4 PCB boards in Altium Designer (Creative Commons) + company logo, and we would need that you add the logo in the boards, then supply the modified Altium Designer files + ODB++ manufacturing files + Gerber manufacturing files

Design a bias network using Cadence Spectre (or other CAD software as longs as I can easily follow your steps).
Must generate a 10uA current with gm = 100uS that cannot vary by more than +-10% over -40 C to 130 C or supply variations of +-10% with a nominal 1.8V supply. You come up with the idea of using a constant gm bias circuit to bias the amplifier

Need a prototype for a project. My needs are:
Hardware
* An Arduino based PCB
* Two temperature sensors, preferably DS18B20
- The first temp sensor attached to a 1,1 meter long cable
-The second temp sensor attached to a 0,2 meter long cable
* A GSM shield, preferably SIM900 or other GSM shield that will work world wide
* Re-chargable battery, preferably

The job is to design a schematic for a product which would meet the following requirements:
Read animal RFID Ear tags(134.2Khz) at a range of 1 meter or more.(This is the difficult part)
It will be made of two parts.1 - RFID Reader, 2 - Antenna
Enclosure design is not required at this stage. Schematic only.

...about to start a Company which produce a product for the gym, similar to the smart watches.
The function and design of it is clearly defined and noted, but now I have to do Gerber files like conductor layers... for the company which do the PCB manufacturing....

I am interested in having a simple breakout PCB board designed. The attached picture shows the preferable dimensions. The overall dimensions are firm, but the hole spacing can be adjusted to meet standards if necessary. Successfull delivery of schematic, PCB, and gerber files will result in prompt payment. Thanks!
